Advances in sample pretreatment and detection of PCBs in the environment
Mwanza, Moses M.; Ndunda, Elizabeth N.; Bosire, Geoffrey O.; Nyamori, Vincent O.; Martincigh, Bice S. (Journal of Hazardous Materials Advances, 2021)Pollution of the environment by polychlorinated biphenyls (PCBs) continues to be a global concern because of their toxicity, persistence, long-range transport properties and ability to bioaccumulate in fatty tissues. PCBs ... -
Molecularly imprinted polymers for the analysis and removal of polychlorinated aromatic compounds in the environment: a review
Ndunda, Elizabeth N.; Mizaikoff, Boris (RSC, 2016)Synthetic receptors and in particular molecularly imprinted polymers (MIPs) are gaining relevance as selective sorbent materials and biomimetic recognition elements for analyzing polychlorinated aromatic compounds (PACs) ... -
Multi-walled carbon nanotubes: innovative sorbents for pre-concentration of polychlorinated biphenyls in aqueous environments
Ndunda, Elizabeth N.; Mizaikoff, Boris (RSC, 2015-07-21)Carbon nanotubes (CNTs) have demonstrated outstanding chemical and mechanical stability, electrical properties, and strong interactions with aromatic compounds owing to the p-electron system on the graphene sheets. Taking ... -

Organochlorine pesticide residues in sediment and water from NairobiRiver, Kenya: levels, distribution, and ecological risk assessment
Ndunda, Elizabeth N.; Madadi, Vincent O.; Wandiga, Shem O. (Environmental Science and Pollution Research, 2018)Production and use of most organochlorine pesticides (OCPs) was banned through the Stockholm Convention on persistentorganic pollutants. However, appreciable amounts are still detected in the environment due to their ... -
Synthesis of stationary phases that provide group recognition for polychlorinated biphenyls by porogenic fragment template imprinting
Ndunda, Elizabeth N.; Mizaikoff, Boris (WILEY, 2015)Molecular recognition based on imprinted polymers results from the polymerization of functional monomers and cross-linkers in the presence of a target analyte (i.e. template), with subsequent removal of the template to ...
